Data from: Analysing biodiversity and conservation knowledge products to support regional environmental assessments

Two processes for regional environmental assessment are currently underway: the Global Environment Outlook (GEO) and Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). Both face constraints of data, time, capacity, and resources. To support these assessments, we disaggregate three global knowledge products according to their regions and subregions. These products are: The IUCN Red List of Threatened Species, Key Biodiversity Areas (specifically Important Bird & Biodiversity Areas [IBAs], and Alliance for Zero Extinction [AZE] sites), and Protected Planet. We present fourteen Data citations: numbers of species occurring and percentages threatened; numbers of endemics and percentages threatened; downscaled Red List Indices for mammals, birds, and amphibians; numbers, mean sizes, and percentage coverages of IBAs and AZE sites; percentage coverage of land and sea by protected areas; and trends in percentages of IBAs and AZE sites wholly covered b y protected areas. These data will inform the regional/subregional assessment chapters on the status of biodiversity, drivers of its decline, and institutional responses, and greatly facilitate comparability and consistency between the different regional/subregional assessments.当前有两项区域环境评估进程正在开展：全球环境展望（Global Environment Outlook，GEO）与生物多样性和生态系统服务政府间科学政策平台（Intergovernmental Platform on Biodiversity and Ecosystem Services，IPBES）。两项评估均面临数据、时间、能力与资源层面的制约。为支撑上述两项评估工作，我们将三款全球知识产品按区域及次区域进行拆分细化。这三款产品分别为：国际自然保护联盟（International Union for Conservation of Nature，IUCN）濒危物种红色名录（IUCN Red List of Threatened Species）、关键生物多样性区域（具体涵盖重点鸟类与生物多样性区域（Important Bird & Biodiversity Areas，IBAs）以及零灭绝联盟（Alliance for Zero Extinction，AZE）保护地），以及保护地球（Protected Planet）平台。本次共提供14组数据引用内容，涵盖：现存物种数量及受威胁物种占比；特有物种数量及受威胁特有物种占比；降尺度后的哺乳类、鸟类与两栖类红色名录指数；重点鸟类与生物多样性区域及零灭绝联盟保护地的数量、平均面积及覆盖率；陆地与海洋保护地的覆盖率；以及完全被保护地覆盖的重点鸟类与生物多样性区域及零灭绝联盟保护地的占比变化趋势。上述数据将为区域及次区域评估章节提供支撑，这些章节将围绕生物多样性现状、其衰退的驱动因素以及制度应对举措展开，同时将极大提升不同区域与次区域评估之间的可比性与一致性。
